Electrical Conduit Installation
The laser sensor cable and all other wiring should be run in separate 1/2" or 3/4" conduit. Do not run any
other cables in the same conduit as the laser sensor cable.
A suitable disconnect should be provided by the installer to allow a controlled power-down.
Run conduit between the laser sensor and the crane's control panel. Putting a slight downward bend in
the conduit at the laser transceiver will help keep dirt and water out. Place a protective end piece on the
open end of the conduit to protect the laser cable from sharp edges.
Pull the supplied laser cable by the end that does not have a connector on it through the conduit, starting
from the opened laser sensor end. Leave enough cable on the laser end so that it is twice as long as the
distance between the end of the conduit and the laser unit (about 2 ft. to 3 ft. [0.6m to 0.9m]). This will
produce a service loop, which will also help keep dirt and water out of the open end of conduit (refer to
Figure 16).
This laser cable consists of four wires. See 4 for wiring information for this cable. Plug the connector into
the laser sensor. The connector is keyed; do not force.
